Allergies

   Allergies are caused when a person’s immune system reacts to something that it comes into contact with that is usually harmless to most people. The immune system produces antibodies in response to these substances that cause allergic reactions (allergens). Then the antibodies cause the cells to release a substance called histamine into the blood stream The histamine then causes the symptoms of an allergy.

   Substances that cause allergies in some people are mostly foods. Typical foods that people develop allergies to are milk and dairy products, eggs, wheat, soy, peanuts and seafood. Foods are the most common cause of allergies in infants and young children. Allergies can also arise from insect bites and stings as well as contact with dust, mold, pollen, animal dander, medications and chemicals.

   Symptoms of allergies vary widely. They can include nasal congestion and runny nose, sneezing, headaches, skin rashes and wheezing among many others.

   Allergies are treated by avoiding or removing the suspected allergen from the person’s environment. Sometimes treatment is indicated with allergy shots or epinephrine for a severe reaction.
